Abstract

PURPOSE:To eliminae false operation such as erroneous reverse travelling by detecting the position of a slewable body to a travelling body and making thereby the diretios of operation of the travelling lever and of advance of a vehicle accord with each other in the captioned device for a loading shovel and the like. CONSTITUTION:The travelling operation levers 11 and 12 deliver their operation with traveling signals VL and VR, while a slewing operation lever delivers a slewing angle signal Vtheta in accordance with a slewing angle by means of a slewing angle detector 23 fitted to a center swivel. And, the slewing angle theta is set to be 0 deg. when a working machine 4 is positioned properly in the front direction to the travelling body 2, while it is set 90 deg. and 180 deg. when the machine is positioned in the right-side and rear directions. In the case when the working machine 4 is positioned on the front side to the travelling body 2, i.e. when the angle theta is in the range from 270 deg. to 0 deg. and to 90 deg., a control signal Sb is employed as it is, and when the working machine 4 is positioned on the rear side to the travelling body 2, i.e. when the angle theta is in the range from 270 deg. to 180 deg. and to 90 deg., the control signal Sb is delivered through the intermediary of a polarity inverting circuit 32.
